David Lewis – Assistant Professor (CV)

I am interested in understanding controls on the movement of nutrients and energy in ecosystems, human-environment interactions, and their implications for ecosystem structure and function. My research presently focuses on freshwater wetlands and intertidal habitats in mixed-use landscapes. I collaborate with natural and social scientists and environmental managers to better understanding biophysical and human controls on ecological processes. My teaching program includes graduate and undergraduate courses on various areas of ecology and environmental science.

Kristine JimenezKristine Jimenez (
Lab Manager and Research Technician

I received my B.S. degree in Biology with a minor in Environmental Soil Science from Penn State University in 2007 and my M.S. degree in Biological Sciences from the University of Alabama in 2010. I am interested in plant-soil-atmosphere interactions and exchanges that occur in forest and wetland ecosystems. Specifically, I’m interested in understanding biogeochemical cycles and their responses to climate change, management regime, and natural & anthropogenic disturbance. Aside from managing the day to day activities in our lab, I am currently working on a project investigating nutrient immobilization in mangrove forests and salt marshes. When I’m not stuck in the mud at our field sites or rolling tins for elemental analysis, I’m usually riding my bike or watching football. (Kristine’s publications)
